Sonoma County embraces denser urban developments

Sonoma County supervisors unanimously approved Tuesday a slate of policy changes intended to pave the way for new types of housing, encourage the construction of smaller, more affordable units and help simplify development in certain areas after last year’s wildfires destroyed more than 5,300 homes.

The policy revisions, which only apply to urban areas where sewers are available, created a category for so-called cottage housing, or clusters of smaller units intended to provide options for people who earn too much to qualify for low-income housing but can’t afford market-rate units. It also created the possibility for building housing in some business and industrial districts, allowing workers to live close to jobs or transit hubs.

The board also altered the county’s policy for how density is assigned to each housing unit in certain zones. That allows for smaller units that can be rented at lower prices, such as micro-apartments under 500 square feet and one- to two-bedroom apartments, to count as a fraction of a unit. Previously, the code allowed a single unit to be any size, making it more attractive for developers to build larger units that generate higher rents.

Now, in an area where 10 units are allowed, a developer could choose to build 10 three- bedrooms units, 15 one-bedroom units or 30 micro-apartments.
